This invention relates to a method and means of re-flutin textile rollsand the like so as to provide said rolls with new flutes and place themin as good, or better, condition. as when new.

An object of this invention is to provide means for rendering textilerolls, which have become worn, capable of use by re-fluting the same andre-allocating the surface thereof and building up the flutes again totheir original condition. I r V r 7 Another object of this invention isto provide a method and means of re-fluting all types of textile rollsby imparting to the surface thereof flutes in all respect, as good as,if not better, than the original surface when the rolls were new.

It iswell known that fluted rolls, when they become worn, cannot bere-fluted by merely passing a file or stationary cutter along I the oldgrooves, as this will produce a roll of less cross-sectional area than anew, roll. This invention, by employing a revoluble cut-v ting tool,does not remove any portion of the metal from the roll, but displacesthe same and forces it radially outward and builds up the flutes totheir original cross-sectionalarea, providing rolls equally as good asnew.

The rolling and cutting members for re forming the flutes are chosen tofit the particular shape of the old groove many particular roll, and inmany instances, these rolling and cutting members must be ground to asto reform the flute without breaking the .metal. Also it might be'notedthat another advantage of the method and means herein employed, is thatit is a cold rolled process so that low places in a portion of the oldrolls will be built up to a thickness corresponding to the remainingportion of the roll for the reason that a certain amount of themetalispushed longitudinally of the roll a short distance by the rolling andcutting tools while at the same time being pressed laterally and seekinga place in which to be deposited,and in this manner a flute having asmooth sidewall is provided which is free from burrs to through thecutting tool; the proper shape so as to be suitablefor a particulargroove in a particular type oftextile roll soas to fit the groove insuch a manner a much greater extent that: are the grooves formed byfiling or" cutting; by means of a stationarycutting tool. Also itis'well known thatby building flutes in this manner that the moleculesare packed together forming a flute whichlis more resistant to wear thanone which is formed by cutting by a file or a stationary cutter; Thus,it is seen by the method employed that a roll may here-fluted and put ina better condition than a new roll.

By means of this process, a smoother flute is provided which causes theyarn or other fiber passing between the rolls to clear the rolls muchbetter than ifnew rolls made by filing .or cutting the flutes with astationary cutter were used. One method heretofore employed. in cuttinggrooves has vbeen a posi tlvely driven rotary cutter which acts in a'manner as'above described but leaving a rough surface to the sidewallsof the flutes.

Some of the objects ofthe invention'hav- :ing beenstated, other objectswill appear as the description proceeds when taken in ings, in which- 7V Figure 1 is a sideelevation of one form of the mechanism which may beused in refluting therolls; y Figure 2 is a plan view of'Figure 1; r Figure 3 is a transverse cross-sectional view taken along the line 33 inFigure 2; Figure 4' is a cross-sectional view taken connection with theaccompanying draw,-

taken Referring more particularly to the drawings, the numerals 10 and11 indicate'suitable supports vfora table 9 which has members 12 and 13secured thereon, said members 12 and 1.3 having upstanding end por- Vtions Hand l5 and the central stud supporting portions 16 and 17 whichhave studs18 and 19 therein on which are pivotally mounted arms 20 and21 which are joined together by means of a rod 22 being secured by meansof stud bolts 23 and 24, and the other end of said members and 21 havesecured therein a square rod 25 by means of stud bolts 26 and 27, and onthis rod 25 are adjustably mounted holding members 28 and 29, each ofwhich have a V-shaped notch 30 in the upper end thereof, said members 28and 29 being adjustably secured on said rod 25 by means of bolts 31,said members 28 and 29 having suitable bearings 33 therein, and theV-shaped notches 30 are adapted to support a textile roll 36' for beingoperated upon.

In the portions 14 and 15 of supports 12 and 1-3 is mounted a square rod37 which serves as a slide for a cutting toolimechanism. "This slide 37is held in position by means of stud bolts 39 and 40, and :on thisslide, a member 42 slidably mounted by having :a suitable bearingportion 43, said member 42 being asplitm'ember held in position by meansof bolts 44, and one portion ofmember 42 projectsdownwardly as at 45 andhas secured thereto cutting tool 46, said cutting tool having aplurality of threaded vholes 47 therein which aread-a-pted to be en-;gaged by stud bolts 48 slidably penetrating holes in the portion 45 ofmember 42. This member, 46 projects laterally and has an elongated slot50 therein in which a plurality of rolling and cutting wheels 51 arerotatably mounted on pins 52 which are fixedly secured in the lowerportion of member 46 and span the slots-50,. These rolling and cuttingdisks 51 are similar to pipe cutting disks and are adapted to follow theold flutes in the roll for building the same up to their originalcondition, The disks 51 may vary in size and if desired, the centralones may be slightly larger than the end ones.

Member 42 has secured therein a stud bolt 55 on which is loosely mountedbearing portion 56 of connecting rod 57 said connecting 110d- 57 beingadjustably mounted in a slot 58 by means of bolt 59 to adjust the lengthof stroke of the cutting tool, said slot 58 being in one of the spokesof wheel 60 which wheel is fixedly secured on a shaft 61 which shaft ismounted in bearings 62 and 63 in supports 64, and on the other end ofsaid shaft a drive pulley 66 is fixedly secured having a belt 67connected to any suitable source of power for driving the same.

Spanning the distance between the sup ports 10 and 11 is arod 70 onwhich is pivotally mounted a lever 71 having a plurality of 7 holes 7 2therein in which the lower end of a ,rod 73 may be adjustably mounted,and the upper end of this rod 7 3 is pivotally secured to rod 22 forlowering one end of members 20 and 21 and pressing the roll 36 in thepath of the cutting tool; Secured to table 9 is a member 7.5 in which issecured a. support 76 which projects laterally overrod 22 and has dulledto provide a roll equivalent all rean eye bolt 77 secured therein towhich is secured a tension spring 78, the lower end of said tensionspring being secured to rod 22, the purpose being to normally hold theroll holding end of members 20 and 21 away from 70 the path of thecutting tool.

Member 71 has a pedal portion 79-on which the foot of the operator isadapted to be placed for controlling the position of roll 36.

In operation, a roll 36 is placed in the mechanism and the member 71 isdepressed which throws the roll in the path of the cutting wheels 51,and the cutting tool slides back and forth on slide 37 and follows theold grooves 80 in the roll.

In Figure 6 it is seenthat the grooves 80 are shallow, as the tips ofthe flutes have been worn down and an elevation of this is shown in thelefthand end of Figure 5. The passtionin Figure 7.. This does not removeany of the metal from the roll but re-allocates the? metal and builds upthe flutesby'pressing the molecules outwardly and upwardly and buildsthe roll to its original condition rand making the cross-section of theroll slightly larger if desired, than its original condition; and then asuitable dressing operation such as emery cloth and the like isperformed on the roll, leaving the tips of the flutes slightly .spectsto a new roll. 3-1

It isd-esire-d to be pointed out that this operation is quite unlike themethod of filing or cutting new grooves, but on the contrary, thismethod and means retains all of the metalof the roll and re-allocates'the mole- T cules and builds up the rolls by providing flutes on-thesame of the same cross-sectional area as a new roll. I

In the drawings and specification, there has been set forth a preferredembodiment" of the invention and although specific terms are employed,they vare used in a generic and descriptive sense only and not forpurposes of limitation, the scope of the invention being setforth in theappended claims. 7
